Easy To Use
Great farm tool!
I have a horse farm with 4 Clydesdales. As you can imagine, my 4-board fencing gets a lot of damage. This saw does the trick with being able to cut boards on site rather than having to go back and forth to the barn w/ electric type. Very easy to use. Long power supply.Cuts smoothly.

Could not stop this saw
Purchased this saw to do small quick jobs so as not to have to pull out the long cords. On its first use the job was larger than expected We used this saw to cut every thing on the job and at the end of the day I was out of energy and the saw still had plenty of battery life to go. The 20 volt battery's are so much better and long running than some of the other brands I have used

Works great for small jobs
Great for a project without electrical outlets or to make a cut without having to drag a cord. Safer than a corded saw.

Easy To Use
Love not having a cord
I've used this saw several times and am very pleased. It's a powerful saw, and not having a cord to get in the way is great. It's also much lighter than my corded saw, so it's easier to hold at odd angles and still be safe. I have several of Dewalt's 20v max tools, so the interchangeable batteries are great too. Overall I'm very happy, and this saw will probably get a lot of use.

Is this circular saw brushless?
Pat on Jun 8, 2015
BEST ANSWER: No,this tool is not brushless.
Are only the impact, hammer drill and oscillating multi tool brushless?
Curtis on Dec 27, 2014
BEST ANSWER: No. The DeWalt Brushless line consists of: Impact driver, Drill Driver, Hammer Drill, Multi-Tool, Framing nailer, String Trimmer, Drywall Screwdriver, and Blower.
The item description is: 20V MAX XR 3.0 Ah Lithium-Ion 6-1/2-in Circular Saw Kit - DCS391M1; I assume the 3.0Ah refers to the included battery. Other sites, including DeWalt's, say that this kit includes a 4.0 Ah premium XR battery. Please confirm which battery ships with this kit. Thanks.
Arnie on Sep 2, 2013
BEST ANSWER: This saw includes a 4.0 Ah battery. We are in the process of correcting our listing.
